$\"\"$

\

Hence, $\"\"$ it satisfies the third condition of the Rolle $\"\"$ s theorem.

\

$\"\"$ is continuous on the interval $\"\"$ .

\

The function is $\"\"$ .

\

Differentiate $\"\"$ on each side with respect to $\"\"$ .

\

$\"\"$

\

$\"\"$ is not differentiable at $\"\"$ .

\

$\"\"$ is never $\"\"$ , thus there is no values of $\"\"$ where $\"\"$ .

\

Even though it does not contradict the Rolle $\"\"$ s theorem because $\"\"$ is undefined when $\"\"$ in which we should not apply Rolle $\"\"$ s theorem.

\

\

$\"\"$ is undefined when $\"\"$ , we cannot apply Rolle $\"\"$ s theorem.
